IMPROVE!) HUB .'EOR CARRIAGE-WHEELS.

The Scheule referred to in these Letters Patent and making part of the same.

To all whom fit may concern:

Be it known that I S. T. F. STERIUK, of \Vasl1ing ton, District ot' Columbia, have invented a new and useful Improvement in` Hubs for Tagons and other Vehicles; and I do hereby declare that the following is a t'ull, clear, and exact description ot the same, ret'- ereuce being had to the annexed drawings, making part of this speciiication, in which- Figure l is an elevation ot' my improved hub, as it appears when ready to receive the spokes of the wheel.

Figure 2 is a moditied t'orm ofthe hub, showing its adaptation tn a velocipede.

Figure 3 is a longitudinal'sectional section through the centre ot' lig. 1, showing the elastic washers which are to be. placed upon either side of the spokes.

Figure 4 is an inside View ot' the loose disk which is moved by the nut, showing the projections thereon, which form the sockets for the spokes.

Figure A5 is a similar view ot' the disk, to be used in the modiiied form ot' hub.

Figure 6 is a longitudinal central section of the Y moditied form.

Corresponding letters in the several figures refer .to corresponding parts.

This invention relates to an improvement in metallic hubs for wagons and other vehicles, and is designed as an improvement upon the one for which Letters Patent were granted to Joseph Abbott, on the 30th day ot'Jauuary, A. I). 1866; and

It consists in the combination and arrangement of its parts, as will be more fully described hereinafter.

A, in the drawings, represents a pipe having an aperture through it for the outer end ofthe axle to pass through, as shown in tig. 3, that portion ot' the pipe which is outside ot' the disk B' being provided with a screw-thread, to receive the disk or dan ged nut G, and the cap-nut l).-

' Upon the inner end of this pipe or hub there is formed a recess, which is larger in diameter than the aperture through which the arm ot' the axle p z sses, which recess or chamber is for the reception of the collar which is usually formed upon the axle.

At a suitable distance from the inner end of the hub or flange a disk, B, is aflxed, which I have shown as being cast with the pipe-portion of the hub, which form ot' construction is the one I prefer; but, as is apparent, this ange ordisk may be screwed upon such pipe, andthus be 4made- .'to perform all the functions which it will it' cast or made a part of the saine by being immovably connected therewith.

Upon the inner face ot' this iiange or disk, or that face which is nearest to the centre of the hubs, a series of projecting Bauges is to be placed, as shown at b in Iig. 4. lhey are to project from such flange or disk for a distance equal to one-halt` of the width otf the spoke, or thereabouts, and be so arranged that the spaces between them shall correspond in number with the spokes of, the wheel, which may be more or less,

according to the views of the constructor.

B' represents a disk of metal, which is to be supplied upon its inner face with projecting anges, in all respects like those above described, and for a similar purpose, and it is to be' provided with an aperture through its centre, of sufficient diameter to permit it to pass upon the pipe-portion of the hub, just within that portion upon which the screw is cut.

lhe construction and arrangement of the flange or disk Band disk B 'are such that, when the disk B is put upon the pipe or portion A of'. the hub, and the projections upon its inner face are brought in contact with the projections upon ange or disk B, a chamber or recess will be formed for the reception ot' the spokes, as clearly shown in ligs. l and 2.

C represents a nut, upon the inner end of which a flange is formed, the diameter of which is somewhat less than that ot' the disk B; while the outer and smaller portion is to be prepared for the reception of a wrench, by being' made sexagonal upon its outer surface, or of any other suitable form. The interior surl'ac'e of this nut is to be faced oli true, so that it may bear firmly against the outer surface ot'thedisk B', so that as this nut is turned upon the thread after the spokes have been inserted intothe recesses formed for them, as above described, they may be pressed between disks B and B, which shouldbe left at some little distance from each other when the spokes are fitted into them, in order that the pressure caused by turning the nut may he received upon their edges when the wheel is new, and so that at any time thereafter such pressnre may be further applied in the event of their becon'iing loose from shrinkage or'other causes.

D represents a nut, which is cylindrical in form for the greater portion ot' its length, but which has, near its (entra-l portion, a sexagonal formation upon its periphery, for the reception ot' a wrench, with Whichto turn the same when it becomes necessary to screw. it upon the inner nut C, in which case it serves the purpose of a jam-nut, and prevents the unscrewing of either. The cavity in this nut does not extend entirely through it, but bears upon its outer end a cap,

as shown in tig. 3, which serves the purpose of excluding the dust from the axle, as well as of making an improved appearance in the hub, and preventing the escape ot' the lubricati11g-material at that point.

a a represent disks ot' rubber or other elastic material, which may be placed next to the disks B B', by

,having apertures formed in them, through which thel projections I) b ot' said disks pass. The object of' these elastic disks is to furnish an elast-io bearing-surface tor the edges of the spokes where they enter the hubs, so

that as the disk B is forged upon the same by means ot' the nut C, the spoke shall not be injured by contact with the metal of the disks.

' b b represent the projections, which are to be formed upon the disks B and B', for the purpose of furnishing sockets for the-spokes, as above described.

In figs. 2, 5, and 6,1 haveshown uinoditcntion of the hub, which is designed to adept it for use use hub for velocipedes. The general construction ofthe hub is the suine as the one'above described, the only difference being, that the uxle passes entirely through the hub, which is rigidly secured thereto, so as to cuus'e it to revolve therewith, instead ot permitting such axle to revolve within such hub, as in the one shown in iigs. l, 3, and 4. j

It will be. seen, by reference to the drawings, that the edges of the disks B B extend beyond the outer ends of the projections b, the object ot' which urrznigement is to furnish additional bearing-surface for the spokes to ,rest upon.

Having thus described my invention,

. what I cluim, and desire to secure by Letters Patent, is-

tially as und for the purpose set forth.

In testimony whereof, I have signed mylname to this specication, in the presence of two subscribing witnesses.
